IMPROVEMENT IN TO'OL FOR IMAKING-` SYPLINTS.

TheSchedule referredto in lthese Letters Patent making part of the same.

To lwhom it may concerne l Be it known that I, CHARLES F. STEWART, ofGornnna,in the county ot' Shiawasseaand State of Michigan, have inventeda new and useful Improvement in vTool for Cutting Window-CurtainSplints; and I do declare that the following is a true and accuratedescription thereof, reference' being had to the accom,- panyingdrawings and to the letters of reference marked thereon, and being apart of this specification, in which- Figure l is avertical'longitudinal ysectional view of my improved plane; Figure 2 isan eleva-tion ot its rear end; and Figure 3 is a front elevation of theplane-iron. Like letters indicate like parts in each figure.

The nature of this invention relates to animprovement in theconstruction of a plane for cutting thin splints from the edge of aboard, which, splints are woven into curtains or shades.

It consists in the employment of a combination and arrangement ofitsseveral parts, inthe progress of the cutter through the timber; also, inthe peculiar formation ot' the stock of the plane with a recess formedin its body by the insertion ot' a tongue near the bottom of its rabbetor groove, through which the splint passes.V

By means of the arrangement described, the splint is raised but verylittle above the horizontalplane ot' the board, and is prevented frombeing made shaky on the under side, as is the case in other planes wherethe splint is discharged from a throat at the top of the stock, splintscut with this tool being perfectly smooth on both sides.

1n the drawingsf- A represents the stock yot my plane, provided with theusual handle a.

In the bottom of the stock is formed arabbet or groove, B, ofthe widthof the thickness of the board from which the splints are cut or shaved.

To the rear o f the plane-iron this rabbet is deeper than in front, andby the insertion of the tongue O a horizontal throat or passage, c, isformed.

The under side of the 4tongue is on a lower plane than the bottom ofthe` groove in front of the planeiron, the difference being thethickness of the splint.

l) is the plane-iron, having a lip, d, turned tol nearly a right anglewith its body and ground to a cutting edge. p

In the body of the iron is cut a recess or throat, E, extending downtothe back of theV lip` d, through which the splint passes into thethroat c of the plane.

The planeiron is secured in the throat or slot blot the plane by awedge, F, in the usual manner, and is set so as to allow the point ofits lip to take a shaving of the required thickness.

A board of the proper length is steamed or soaked to soften and toughenit. It is then secured edge up in a vise. The operator then shaves oii`the splints in the usual manner; each splint is 'lifted but, thethickness 'of the lip d above the edge of the board, its end passesthrough the slot E of the Aplane-iron into the passage c of the stock,whence the splintis discharged when the cut is completed.

It will clearly be seen that the splint cannot shake or check on itsunder side when out with this tool, as it is not bent upward to split itoft in advance of the cutter, as when cut with planes of other patterns,nor is it liable to break from the same cause. Each splint is smoothlyshaved on both sides.

W hat I claim as Ilnyinventiou and desire to secure by Letters Patent,is

In combination with the plane-iron el (l E, the arrangement ot thepassage e, the tongue C, and the groove B, when constructed andoperating as and for the purposes aforesaid.

CHARLES F. STEWART.
